IAR Visual State

IAR Visual State is a tool for design and code generation. It is used to graphically design state machines and generate C,C++, C# or Java source code.

  • As complexity increases, how do you ensure that you capture the complete design in code? 
  • How can you make sure you keep on schedule when you add complexity to your project?
  • How can you ensure all parts works together when you are a large team developing a project?

With IAR Visual State, you can speed up time to prototype and shorten your time to market. At the same time, you ensure the code quality and smart features enable you to organize and modularize your design for efficient team work. Because the tool is made for embedded systems, it enables you to use state machines in an easy and intuitive way, with no unnecessary features to maneuver among.

  • Generates very compact code
  • Based on UML
  • Provides support for hardware debugging with direct feedback in the state machine design: Instantly see which state configuration is active and which transition got you there
  • Tightly integrated with IAR Embedded Workbench
  • Automatically generates documentation
  • Includes tools for validation and verification
